I've done some research on this but haven't found the answer. I have an older Windows XP desktop computer and a laptop with Windows Vista Home Premium. From the Vista laptop, I can access the files from the XP computer fine. However, I cannot access files on the Vista laptop from the XP desktop computer. Here are the settings for the Vista laptop: In Network and Sharing Center, Sharing and Discovery, Public Folder Sharing is On. Password protected sharing is off. On the hard drive I want to share, Under properties->sharing tab->advanced sharing the Share This Folder box is checked, and under permissions, Everyone is selected as well as Full Control. However, from my XP desktop when I try to access the drive, I receive an error dialogue that indicates that the computer is not accesible and I don't have permission to access it. What am I missing?
